MicroRNA-382 silencing induces a mitonuclear protein imbalance and activates the mitochondrial unfolded protein response in muscle cells

Johan Auwerx, Pénélope Andreux, Xu Wang, Norman Lionel Moullan

Proper mitochondrial function plays a central role in cellular metabolism. Various diseases as well as aging are associated with diminished mitochondrial function. Previously, we identified 19 miRNAs putatively involved in the regulation of mitochondrial m ...

Co-expression of CCT subunits hints at TRiC assembly

Oksana Andrei Sergeeva

The eukaryotic cytosolic chaperonin, t-complex polypeptide 1 (TCP-1) ring complex or TRiC, is responsible for folding a tenth of the proteins in the cell. TRiC is a double-ringed barrel with each ring composed of eight different CCT (chaperonin containing ...

Detection of mRNA by Whole Mount in situ Hybridization and DNA Extraction for Genotyping of Zebrafish Embryos

Andrew Charles Oates, Rachna Narayanan

In situ hybridization is used to visualize the spatial distribution of gene transcripts in tissues and in embryos, providing important information about disease and development. Current methods involve the use of complementary riboprobes incorporating non- ...

Label-free detection of hypoxia-induced extracellular vesicle secretion from MCF-7 cells

Philippe Renaud, Sandro Carrara, Tugba Kilic, Ana Teresa De Sousa Valinhas

Nanoscale extracellular vesicles (EVs) including exosomes (50–150 nm membrane particles) have emerged as promising cancer biomarkers due to the carried genetic information about the parental cells. However the sensitive detection of these vesicles remains ...

The Chaperone and Redox Properties of CnoX Chaperedoxins Are Tailored to the Proteostatic Needs of Bacterial Species

Camille Véronique Bernadette Goemans

Hypochlorous acid (bleach), an oxidizing compound produced by neutrophils, turns the Escherichia coli chaperedoxin CnoX into a powerful holdase protecting its substrates from bleach-induced aggregation. CnoX is well conserved in bacteria, even in non-infec ...

Statistical Analysis of Protein Sequences: A Coevolutionary Study of Molecular Chaperones

Duccio Malinverni

Recent advances in DNA sequencing technologies led to the accumulation of enormous quantities of genetic information available in public databases. This rapid growth of available biological datasets calls for quantitative analysis tools and concomitantly o ...

EVIR: Chimeric receptors that enhance dendritic cell cross-dressing with tumor antigens

Michele De Palma, Mario Leonardo Squadrito, Chiara Cianciaruso, Sarah Kate Hansen

We describe a lentivirus-encoded chimeric receptor, termed extracellular vesicle (EV)-internalizing receptor (EVIR), which enables the selective uptake of cancer-cell-derived EVs by dendritic cells (DCs). The EVIR enhances DC presentation of EV-associated ...

QstR-dependent regulation of natural competence and type VI secretion in Vibrio cholerae

Melanie Blokesch, Sandrine Stutzmann, Candice Stoudmann, Milena Jadwiga Jaskolska

During growth on chitinous surfaces in its natural aquatic environment Vibrio cholerae develops natural competence for transformation and kills neighboring non-immune bacteria using a type VI secretion system (T6SS). Activation of these two phenotypes requ ...

The double-edged toxins

Mario Gonzalo Garcia Arraez

Many insect species are associated with endosymbiotic bacteria which have the particularity of living within host tissues. Endosymbionts benefit from this stable and nutritious environment, while providing ecological advantages to their host, such as prote ...

Three branches to rule them all? UPR signalling in response to chemically versus misfolded proteins-induced ER stress

Maurizio Molinari

Study of the unfolded protein responses (UPR) is mainly addressed by challenging eukaryotic cells with chemical compounds that impair calcium, redox or glycan homeostasis. These dramatically alter the endoplasmic reticulum (ER) environment and function, bu ...
